Hi all, hopefully someone can help me, I think I'm stuck. I want to
replace one of my drives, a 4gb in my physical volume with an 18gb
drive. I have no more free drive slots, so I need to reduce it out of
the set first. I've created plenty of room across the volume to do it.
I'm just having problems finding what I need to do now-- I think I need
to resize my filesystem, but not sure, and if so, not sure how. After
that I think I can doa lvreduce and pvmove, or something along those lines.
Here is my pvscan -- sdb1 is the one I'd like to replace:
BBM:~# pvscan
PV /dev/sdb1 VG Vol1 lvm2 [4.23 GB / 0 free]
PV /dev/sdc1 VG Vol1 lvm2 [8.47 GB / 0 free]
PV /dev/sdd1 VG Vol1 lvm2 [8.47 GB / 0 free]
PV /dev/sde1 VG Vol1 lvm2 [8.47 GB / 0 free]
PV /dev/sdf1 VG Vol1 lvm2 [8.47 GB / 0 free]
Total: 5 [38.11 GB] / in use: 5 [38.11 GB] / in no VG: 0 [0 ]
Any help would be GREATLY appreciated, thanks :)
N/M. I guess I just needed to post for help to get myself motivated. :)
I finally found the few pieces of the puzzle I was missing.
Here's what I did for reference:
BBM:/home/jzach# e2fsck -f /dev/Vol1/shared
BBM:/home/jzach# resize2fs -p /dev/Vol1/shared 25G
BBM:~# lvreduce -L -5G /dev/Vol1/shared
BBM:~# pvmove /dev/sdb1
mirror: Required device-mapper target(s) not detected in your kernel
BBM:~# modprobe dm-mirror
BBM:~# pvmove /dev/sdb1
vgreduce Vol1 /dev/sdb1
